Check Digit Verification of cas no

The CAS Registry Mumber 342376-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,3,7 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 342376-62:
(8*3)+(7*4)+(6*2)+(5*3)+(4*7)+(3*6)+(2*6)+(1*2)=139
139 % 10 = 9
So 342376-62-9 is a valid CAS Registry Number.

Conformationally restricted glutamic acid derivatives: Asymmetric synthesis of 4-substituted 4,5-dihydro-3(2H)-pyridazinones

Alvarez-Ibarra, Carlos,Csák?, Aurelio G.,Gómez de la Oliva, Cristina,Rodríguez, Eliazar

, p. 2129 - 2131 (2007/10/03)

The synthesis of optically pure 4,5-dihydro-3(2H)-pyridazinones substituted at C-4, which can be considered conformationally restricted cyclic Glu derivatives, has been accomplished by the asymmetric γ-alkylation of α,β-unsaturated glutamyl sultams under PTC conditions followed by reaction with hydrazines.
